Hands down, the warmest suit on the market. Featured in all FUSEFLEX suits, FUSEFLEX STICHLESS SEAM TECHNOLOGY eliminates the need for stitched seams and strips away all excess taping. The razor-thin molecular bonding process reduces the amount of tape needed by 60% over traditional 2x taping methods to completely seal the seam, which makes it the warmest suit Quiksilver offers.
